Megagrocer is a grocery chain that operates five stores. The stores are supplied with produce, meat, dairy, and dry goods by six separate vendors. In addition to the stores, Megagrocer maintains an ecommerce site through which customers can order and pay for groceries. The groceries are packed and delivered to customers from one of the five stores in a Megagrocer van by that store’s personnel. Think about the accounting information systems that Megagrocer might use.

- What types of source documents might be collected by Megagrocer to be processed by its accounting information systems?
1. Purchase orders
2. Packing slips
3. Invoices
4. Canceled checks
5. Supplier Invoices
6.Cash Register Records
7. Employee Earning Records
8. FIFO (first in, first out) and
9. LIFO (last in, first out)
:confused:

- Why are those documents important?
